CXA2534Q Datasheet | Sony Semiconductor Solutions

4-Channel CD Motor Driver Description CXA2534Q is a 4-channel H-bridge motor driver IC designed for portable CD systems. It has a built-in DC to DC converter controller that allows voltage step-up to typically 3.2 V; this voltage can be used to power the system DSP, SSP and micro-controller. In addition, it also provides a PWM regulated power supply to the H-bridge output stage so as to ensure high efficiency. Features - 4 channels of H-bridge drivers - PWM regulated power supply for H-bridge output stages - Step-up DC to DC converter controller for system power supply - Start and off controls with soft start capability - Reset pulse - Short circuit protect - Over-voltage protect - Low battery voltage detection - Rechargeable battery charger - General purpose operational amplifier - Thermal shut-down for battery charger and Hbridge driver (170 °C/140 °C) - Direct interface with wired remote controller possible Applications Portable CD player Structure Bipolar silicon monolithic IC 48 pin QFP (Plastic) Sony reserves the right to change products and specifications without prior notice.
